RAIL'JoInT CHAIR.

Application filed March `4,

To all' 'whom it mag/concern:

Be it known that I, JOSEPH J. MARKOVICH, a citizen of the UnitedStatesof America, residing at Uniontown, in the county of Fayette and State ofPennsylvania, yhave invented certain new and useful Improvements 4inRail Joint Chairs, ofvwhich' the followingv is a specification.

This invention relates tocertain new and useful improvements in railjoint chairs and has particular reference to a combined joint chair andsh plate connected together in a manner to prevent relative movementsbetweenthe elements. f

The primary object of the invention resides in the provision of arailjoint chairV wherein rail engaging clamps are 1nter' locked with thejoint chair with the usual form of spikes for retaining the railengaging clamps in their operative positions.

Another object ofthe invention has referf ence to a novel form of shplate associated with the joint chair, the lower edge ofthe irish plateextending in proximity of the base iiange of the rails with meanscarried by the joint chair iin-losingv the lower edge of the fish plate.A j

With the above general objects in view and others that will appear asthe nature of the invention'is betterunderstood, the same consists ofthenovel form,` combination and arrangement of Aparts hereinafter morefully:

described, shown in the Vaccompanying drawing and claimed.

Referring'V more 'in detail to the accompanylng drawing, andparticularly to Fig-V ures '1 to`6 there 'is illustrated a joint chairfor supporting; meeting rail ends 1, the chair embodyingwawbase plateQL-carryingv an integral' fish' plate. lSat one side thereof for en`vgagement withthe base iange, webs and adjacent'sides of' the'railheads,.the upper or Y to facilitate the passage of spikes 7 that tie Sasshown linenter the supporting 2 carries an outwardly directed anchoringstrip 9 ateachend thereof, the strips 9 being provided @with .T-shaped-`openingsV 10 having 'enlarged' ends 11v for the' reception Iof theinterlocking rail engaging clamps. 12. Each clamp embodies a shankportion havinga baseV block 13 and a'clamp head 14 upon The oppositeside edge offthe-base'plate the upper end thereof, the base block 13being inserted through the enlarged end 11 of the strip 9 andsubsequently shifted into the smallerI end of the opening 10 tofacilitate the positioning of the rails 1. Vhen the rail is properlylocated in the joint chair, the clamps 12 are moved vthrough the slots10 in a direction toward the rail to cause the clamps 14 to engage thebase flange of the rail,-the engaging clamps being retained in positionby thespikes 15 entering the eX- tremeouter end of the `opening forreception in the tie 8, and thereby anchoring the chair and rails to thetie. As shown in Figure 3, the filler plate 16 is interposed between thebase plate 2 of the chairv and the tie 8, compensating for the depth ofthe base block 13 of the rail engaging clamp as will be readilyunderstood.

A removable fish plate is associated with the joint chair and the rails,and is positioned at the side of the rails opposite the integral fishplate 3, the removable fish plate embodying a rail web engaging plate 17of the same length as the joint chair, the plate 17 carrying anoutwardly directed extension arm 18 for engagement with the base flangeofthe rail, with the arm 18 disposed between the chair anchoring strips9 as shown in Figures 1 and 2 with a depending lip 19 formed at theouter end Vof the arm 18 for engagement with the outer edge of the railbase ange. As shown more clearly in Figures 21, 2 and l the bottom wall2 of the chair has an upwardly extending lip 2O interm'ediate theanchoring lip extensions 19, the lip 2O being positioned outwardly ofthe fish plate lip 19 enclosing the same and cooperating therewith in avmanner to prevent outward movement of the fish plate 17 relative to therjoint chair. To anchor the plate 17 tothe rail and chair, a pluralityof registering openings are formed in the integral fish plate 3, therail webs and the removable plate 17 for the reception of locking bolts21.

'From the above detailed description, it is believed that theconstruction and operation of the invention as disclosed in said figureswill be readily understood. The rail engaging clamps are first insertedin the enlarged ends 11 of the base plate openings 9 to be moved to theouter ends of the openings 10, the meeting rail ends 1 being thendisposed inthe joint chair with the remov! able fishplates 17 engagingthe rails and disposed in proper relation to the meeting rail ends andVanchored `thereto by the lock bolts 21, it being noted that the lipextension 19 upon the removable fish plate armr18 is disposed inwardlyof the lip '2O carried by the base of the joint chair intermediate theanchoring strip sections 9. The rail engaging clamps are then movedthrough the slots 10 i in adirection toward the base anges of the rails,to cause the clamp heads 14 to engage therail as shown in Figure 2spikes 15 being inserted into the outer ends of the openings 10 forengagement with the tie 8 to anchor the joint chair and rails to thetie, it being understood that the spikes 7 inserted through the openings6 in the anchoring strips 5 will securely bind the Y'chair' to the tieat the opposite side thereof. The filler plate 16 interposed between thejoint chair and the tieY to compensate for the height or depth of thebase block 13 of therail engaging clamp, provides a rigid andsubstantial mounting for the joint chair and a strong support for therai-l. A modified form of the invention is shown in Figures 7 to 11, thefish plates 3 being formed integral` with the base plate `2 of the jointchair while integrally formed screw bolts 21 for the receptionV clamphead 26 and a retaining Ei"shaped base 27. The shank 25 of the railengaging clamp is normally of the form shown in Figure 9, whereby thesame may be inserted through the opening 23 of the base plate 2 vat thelower side thereof and subsequently flattened or distorted to cause thesame to assume the formation shown in Figure 10, the clamp 25 beingpermanently mounted in the base pla-te 2 of the joint chair for the freesliding movement. `When the rail engagingclamp 25 is moved intoengagement with the base flange rof the rail as shown in Figure'll, a

spike 7 or 15 is inserted into the other end of the opening 23 to retainthe rail engaging clamp in engaging position with respect to the baseflange of the rail.

While there are herein shown and described the preferred embodiments ofmy invention, it is to be understood that minor changes in construction,combination and arrangement of parts may be made withoutdeparting fromthe spirit and scope of the invention as claimed.

Having thus described the invention, what I claim is:-

1. In a joint chair of the type described, a base plate, anchoringstrips extending from the opposite sides thereof adjacent the ends, anintegral fish plate carried by oneA side or" the-base plate, theanchoringstrips at one side of the base plate having T-shaped openingstherein, rail engaging clamps i11- terlockingly received in the T-shapedopen-` ings and means for retaining the clamps in engagement with therails.

In a joint chair of the type described, a base plate, anchoringstrips extending from the opposite sides thereof adjacent the ends, anintegral fish plate carried by one side of the base plate, the anchoringstrips at one side of the base plate having T- shaped openings therein,rail engaging clamps interlockingly received, in the T- shaped openings,means for retaining the clamps in .engagement with the rails, aremovable iish plate arranged at the opposite side of the rails, adepending lip carried by the lower edge of the removable fish plate, Y

and an upstanding lip carried by the base plate of the chair disposedoutwardlynof the fish plate lip, the cooperating lips of the lish plateand chair base plate-being dis- Y ends, an integral fish plate carriedby one j side of the base plate, the anchoring strips at one sideof thebase plate having T- shaped openings therein, rail engaging clampsinterlockjngly received in the T- shaped openings,'means for retainingthe clamps in engagement with the rails, a removable iish plate arrangedat the opposite side of the rails, a depending lip carried by the loweredge of the removable ish plate, an upstanding lip carriedV by the baseplate of the chair disposed outwardly ofthe fish plate lip, thecooperating lips of the fish plate and chair base plate being disposedbetween the adjacent anchoring strips, and a filler strip interposedbetween the base plat-e of the chair and a supporting tie.
